VUNITED I STATES i:PATENT OFFICE@ IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 49,450, dated August 15, 1l$65 To alt whom it may concern:

Be it known that I, WILLIAM H. SLONAKER,

panying drawings, making a part of this specii iication, in which- Figure l is a l'ront elevation ot the improved churn. Fig. 2 is a vertical transverse section through the churn. Fig. 3 is a horizontal section through the standards and dash-rods. Fig. 4 is an end view, showing the manner of' attaching the standards to the ends of the churn-box.

Similar` letters of reference indicate corresponding parts in the several figures.-

This invention relates to that class of chorus which have a number of dashers that'j'are operated by cranks so as to receive vertical reciprocating motions.

The object of my invention is to provide, in such ch urns, a means for guiding the dash-rods so that they will allvmove freely in vertical lines, and to so apply the guide that the dashers can be readily removed from the churn-box or replaced therein atpleasure, as will be h ereinafter described.

Another objectof my invention is to provide for detaching the dash-rods from their pitmanrods, and also for detaching the standards, which support the movable parts of the churn, fromjhthe churn-box, so that the churn can be packed up in a small compass when notin use, or for purposes of transportation, as will be hereinafter described.

To enable others skilled in the art to understandhny invention, I will describe its con-- struction and operation.

In the accompanyingdrawings, Arepresents a churn-box of arectan gulai` oblong form, which churn-box by means of dovetail tenons df?,

which are secured rigidly to said box, and which receive theslotted endsof the standards, as shown in Fig. 4. A screw-pin,- b, projects from each one of the tenons d land receivesa nut, c, upon it, by means of which the ends of the standards are held in their places. In addition to these fastenings, the lower ends ot' the standards are beveled on eacliside, so as to enter the `dovetail slots or notches through the projectingportionseof thetop of thechurnbox, as shown in Fig. 4. By thus attaching the standards B B to the churn-box A they can be detached at pleasure by simply loosening the thumb-nuts c c and lifting the standards vertically out of their seats.

G'represents a crank-shaft, having as many cranks as there are dashers. In the drawings four cranks are shown; but any number may be employed, according to the length `of the churn-box and the number of dashers which it will receive. are attached, as will be hereinafter described, and to the lower ends ot' these rods the dashrods h lr are pivoted, as shown in Fig. 1. These dash-rods pass down through guides j jaud through the top of the churn-box, and are held in vertical position by means ot' said parts.

The guides j j are notched and halved together, so as to receive between them the rods It li, and the ends of the guides are let into recesses formed in the standards B B, and secured in place by means of aturn-buttomt, as

vertical positions and allowing them to receive a vertical motion. v

When it is desired Ato remove the dashers the button tis turned to one side, the rod t j and coyers of the churn-box removed, and the dash-rods disengaged from their pitman-rods.

The dash-rods have hooks k secured on their upper ends, whichihook over pins in the notched ends ot the pitman-rods, which pins are so arranged that when rods h h are attached to the pitinen and brought down to a vertical position they will not become disengaged therefrom.

The dashers receive their motion from a crank-shaft having four cranks at right angles To these cranks pitman-rods g g` Thus it will be seen that these rods have to each other. This shaftis driven by means of y a large spur-wheel, D, onv a crankshaft, D', which wheel engages with the teeth of a pinion, E, on the crank-shaft C. By turning the crankshaft D the crank-shaft U will receive a rapid motion, which is communicated to the dashers.

There is nothing peculiar in the dashers. They may be made in vany suitable manner, and they may be perforated or imperf'orated, as may be desired.

From the above description it will be seen that I am'enabled to attach or detach the dashers at pleasure for the purpose of cleaning out the churn-box and these dashers, and keeping the churn always sweet.

When it is desired to pack up the churn for transportation the entire frame-work which supports the dashers can be taken to pieces and put together in a very compact form.
